An intraocular lens (IOL) is an implanted lens in the eye, usually replacing the existing crystalline lens because it has been clouded over by a cataract, or as a form of refractive surgery to change the eye's optical power. It usually consists of a small plastic lens with plastic side struts, called haptics, to hold the lens in place within the capsular bag inside the eye. Sir Harold Ridley was the first to successfully implant an intraocular lens on November 29, 1949, at St Thomas' Hospital at London. The intraocular lens found widespread acceptance in cataract surgery in the 1970s, when developments in lens design and surgical techniques had come about. Replacement of the crystalline lens with a lens is now routinely done in most centres worldwide. By the 21st century millions of IOLs are implanted.
Natural Yellow lens is superior to other yellow IOL material because it filters out harmful violet rays protecting the retina without blocking needed blue light still allowing some beneficial violet rays to enter, providing complete natural protection without losing contrast sensitivity or color perception. Recent independent investigations have shown that current blue blocking IOLs cause a loss in contrast sensitivity and color perception. There is nothing more natural than using the same chromophore that nature intended when the natural lens must be replaced.
